Which term describes a formal order issued by a court?

The term that describes a formal order issued by a court is "injunction." An injunction is a legal remedy that requires a party to do certain acts or prohibits them from doing certain acts. It is a directive issued by the court commanding a person to stop or start a specific action, ensuring compliance with the law or protection of rights. The nature of an injunction can be temporary or permanent, and it is often used to prevent harm or to maintain the status quo until a legal matter is resolved.

In contrast, a summons is a document that notifies a person that they are being sued and requires their appearance in court, rather than being an order from the court itself. A subpoena, on the other hand, is a legal document that orders an individual to appear and testify in court or produce evidence. Lastly, a verdict is the decision made by a jury or judge at the end of a trial, reflecting the outcome of the case rather than an order issued by the court.
